I did look at this, however I didn't see anything that seemed tasetful to implement and as I look at it more I'm not sure any naive VMM is going to have a good time with this ABI, the fact that registers can get hotplugged depending on the current mode creates all kinds of fun. I left things alone for now, I'll take another look and see if I come up with better ideas.
